Another object is to supply a needle holder provided with special meansfor gripping the instrument, which means designate the proper anatomicrole to at least four fingers of the surgeons hand.

Another object is to provide a needle holder which enables a firm andnimble hold of the instrument.

Still another object is to provide a needle holder which engages morefingers than the two ring needle holders, without making the handle ofthe instrument more complicated.

Another object is to provide a bicapsular needle holder, the capsules ofwhich have the indispensable length so that the ring like member willnot exert any substantial pressure on the fingers.

Another object is to provide a capsular member for the forefinger, sothat the latter is conveniently raised whereby the pressure of the ringlike member for the thumb does not become uncomfortable over the thumbsdorsal surface.

A still further object is to provide the capsular members with aninternal striated surface imitating the capillary grooves by means offine fiutings which benefit the retention of the instrument.

.A still further object is to provide an arcuate lever for the middlefinger located between the ring like member for the ring finger and thecapsular member for the forefinger.

These and further objects and advantages of the invention will becomeapparent in the course of the following description. In order that theinvention may be more clearly understood and readily carried out, apreferred embodiment thereof has been illustrated in the accompanyingdrawings, by way of example.

In the drawings:

Figure 1 is a perspective view of a bicapsular grip applied to a needleholder.

Figure 2 is the same needle holder as shown in Figure 1 but illustratingthe position of the surgeons hand when gripping the latter.

Figure 3 is a plan view of the needle holder of Figure 1.

Figure 4 is a detail of the capsular member integral with the ring likemember, for the thumb.

Figure 5 is a detail in lateral elevation of the capsular member for theforefinger.

Although reference is specially made to a needleholder it is to beunderstood that the bicapsular grip may be applied to other similarsurgical instruments and the scope of this invention has to beinterpreted along these lines.

It may be appreciated from the accompanying drawings, that thebicapsular needle holder i comprises a first branch 2 and a secondbranch 3, pivotally linked together by means of pivot l or the like,each branch 2 and 3 having a free end portion 2' and 3, respectively.

The other end of said branches 2 and 3 con stitute the needle holderjaws 5 and 6, which are of the known type and therefore will not bedescribed. f

The free end portion 2' is integral with a first ring like member 1,,which ring like member l is bevelled so that the inner surface 7 thereofwill, enter throughout substantially its entire length with the thumbssurface without exerting a pressure thereon.

For convenience of describing said ring like member the latter isdivided into an outer portion la and an inner portion lb, by axis A. Theinner portion 7b is integral with a first capsular member 8, theconcavity of which is directed towards the outer portion la. Said firstcapsular member 8 has an outer wall 8' (see Figure 2) directed towards asecond ring like member 9 integral with the free end portion 3, as willbe later explained.

The inner surface 8" of the first capsular member a reproduces exactlythe anatomy of the thumbs ball and it even imitates its capillarygrooves by means of fine flutings it which benefits the retention of theinstrument. A scale shape plate H, the concavity of which is acontinuation of the concavity of the first capsular member 8, isintegral with said first ring like member '5 and adjacent to the freeend portion 2 and so located that the axis A is approximately an axis ofsymmetry therefor. Said scale shape plate I! buts against thecorresponding lateral portion of the thumb and thereby decreases thepressure of the rings top edge l0 and distributes said pressure in amore uniform manner, whereby the tactile sensitivity is considerablyincreased. The lower portion of the first capsular member 8 is slightlycurved, as may be best seen in Figure 3, so that the tip of the thumbbuts thereagainst, whereby slippage of the ring like member i towardsthe root of the thumb is avoided.

The second capsular member 9 is also bevelled but in opposite directionas said first capsular.

member I as may be appreciated from axis B and C, respectively, so thatalso this second ring like member 9 has its inner surface 5 soorientated that it enters throughout its substantially full length incontact with the ring finger, as best seen in Figure 2, wherefrom it isalso possible to understand that the instrument is so gripped by thehand that it contitutes a prolongation thereof, or in other words it issubstantially parallel to the forearm of the surgeon.

-A second capsular member 12 (see also Figure 5) is fixed to said secondbranch 3, by means of a rib IS. The cavity of said second capsularmember I2 is directed towards the pivot 4 and the capsular member is soshaped that said cavity is the negative of the forefingers tip, ball andpart of the middle phalanx, and since the fore finger is usuallyslightly bent the top portion l2 of said second capsular member I2 isslightly bent backwards towards said free end 3'. The inner surface l2"of said second capsular member I2 is also provided with line flutingswhich benefit the retention of the instrument.

Finally the second branch 3, in the preferred embodiment, is alsoprovided with an arcuate lever It the concavity of which is directedtowards said second capsular member and which arcuate lever isprojecting from said second branch 3 in substantially the same plane assaid second ring like member 9.

As maybe best seen in Figure 2 the first and second-ring like members iand 9 as well as the arcuate lever 14 project laterally from therespective branches 2 and 3 so that the thumb,

the middle finger and the ring finger will holdthe instrument from theoutside, whilst the second capsular member I2 is so located that theforefinger will be located on thetop of the ingees I, I I a aiereeytastier eiiettiea r the inst-r menuearn fishijai y a'pivot; ea'cnb anonfi'avi g'drregend ptrt n on the same side's! e fl l s p II I I II sai-pita enl stsshearing-nee meeiter ixe nebranchsiv tegrai" n said fr'assertion-trend "t vot; ea: eh i,- ember dserene sveiiee ring like;
